Chemistry – College PrepItalics reflect 21 st Century Skills implementationCourse Title: ChemistryUnit Title: GasesContent Standards/Performance Goals:Chemistry - Conservation of Matter and StoichiometryThe conservation of atoms in chemical reactions leads to the principle of conservation of matter and theability to calculate the mass of products and reactants.Scientific Inquiry, Literacy and NumeracyScientific inquiry is a thoughtful and coordinated attempt to search out, describe, explain and predictnatural phenomena.Scientific inquiry progresses through a continuous process of questioning, data collection, analysis andinterpretation.Scientific literacy includes the ability to read, write, discuss and present coherent ideas about science.Scientific literacy also includes the ability to search for and assess the relevance and credibility ofscientific information found in various print and electronic media.Scientific numeracy includes the ability to use mathematical operations and procedures to calculate,analyze and present scientific data and ideas.Haddam Killingworth High School Expectations for Student LearningThe Haddam Killingworth graduate will problem solveThe Haddam Killingworth graduate will access and analyze information.Enduring Understandings: Students will understand that . . . . .Gases can be modeled by the kinetic molecular theory.The variables of pressure, volume, temperature, and number of particles describe various aspects of agas’s situation.Essential Question(s)What do the variables pressure, volume, temperature, and number of particles describe about a gas?What are the mathematical relations between a gas’s pressure, volume, temperature, and number ofparticles?Students will know . . . .What the variables pressure,volume, temperature, and numberof particles describe about a gas.What the mathematical relationsbetween a gas’s pressure, volume,temperature, and number ofparticles are.The name, formula, andmathematical details of various gaslawsIdeality v. real gasesStudents will be able to . . . .Know the symbols, meaning, units, and collisionaspect of the variables pressure, volume,temperature, and number of particlesQualitatively state and explain Boyle’s, Charles, andAvogadro’s Laws.Identify directly proportional and inverselyproportional relationships between variablespressure, volume, temperature, and number ofparticlesUnderstand independent variable, dependentvariable, and controlled variables as they apply toBoyle’s, Charles, and Avogadro’s Laws.Calculate utilizing Boyle’s, Charles, Combo, andAvogadro’s Laws.Apply gas law theory to experimental conditions andRevised 2009Contributor: Jim DanielsProperty of RSD #1722
